We are prepared for possible power cuts – My OK and OK Online will remain functional

Dear Customer

Discussions are ongoing regarding electricity shortages and subsequent power cuts this winter in Finland. Fingrid, Finland’s transmission system operator has announced that in case of electricity shortage the power cuts will last two hours.

OK Perintä has prepared for power cuts by making sure that our web services My OK and OK Online are fully functional even during the power cuts. As we have customer service in several cities, we strive to keep part of our customer service open if the power cuts are local. Please note that the queues at this point may be longer. 

The power cuts do not impact our letters, but the delivery is dependant on the readiness of the post office.  

Best regards 

OK Perintä
